Hi Ben_01880,
This is a known issue with DAQmx Base and Mac OSX. It happens when OSX boots into 64bit kernel instead of the 32bit kernel that DAQmx Base requires. Here is a workaround from the DAQmx Base help file:
"Xcode 3.2 or later will default to 64-bit
(x86_64) architecture when calling gcc on 32-bit OSX 10.6 if the system
hardware is 64-bit. This will result in errors during compilation. To resolve
these errors, force gcc to use 32-bit (i386) architecture in 32-bit OSX
installations by appending '-arch i386' to the flags in your Makefile:
flags=-O2 -arch i386"
There is also an article on the Mac support website that shows how to force OSX to boot into the 32-bit kernel on a per-boot basis:

Finally, there is a long NI discussion forum about this issue and how people were able to resolve it. I link you to it as it is a good resource:

I hope this helps, let us know if you are still having problems!
